A more thorough explanation:

Term: Adventitia Dos
Definition: Adventitia dos is a type of dowry given to a woman by someone other than her father. This type of dowry is recognized in civil law. It is also known as "dowry brought in from outside." Adventitia dos is different from dos profectitia, which is a dowry given by the wife's father.
Example: If a woman's uncle gives her a sum of money as a wedding gift, this would be considered adventitia dos. This is because the money was given by someone other than the woman's father. Another example would be if a woman's employer gives her a valuable piece of property as a wedding gift. This would also be considered adventitia dos.
Explanation: These examples illustrate adventitia dos because in both cases, the dowry was given by someone other than the woman's father. The dowry is considered adventitia dos because it was brought in from outside the woman's family. This type of dowry is recognized in civil law and is different from dos profectitia, which is given by the woman's father.
